Abstract
The utility model provides a floating roof storage tank with a counterweight structure, which is characterized in that a floating roof is provided with a counter weight, one end of a rope or a chain is connected with the floating roof, and the other end bypasses a guide wheel to be connected with the counter weight; the gravity of the counter weight, the floating force of the floating roof, and the gravity of the floating roof, the gravity of an object loaded on the floating roof, corresponding friction resistance and the like form a balance relationship through the guide wheel. For the floating roof storage tank with the counterweight structure, the whole structure of the storage tank is simplified, the production cost and maintenance cost of the storage tank are greatly saved; in addition, firefighting equipment, fire extinguishing agent and the like can be arranged on the floating roof according to needs so as to realize the instant injection of the fire extinguishing agent, meanwhile, water discharge equipment can be arranged on the floating rood, so that the water discharging is more convenient. For the floating roof storage tank with the counterweight structure not only the safety performance of the storage tank is greatly improved, but also the production cost is greatly lowered for the floating roof storage tank.
Description
Technical field
The utility model relates to floating roof tank.
Background technology
The floating top of floating roof tank (comprising internal floating roof tank and outer floating roof tank) is one and swims in the lip-deep floating top cover of storage liquid, fluctuate along with the input and output of liquid storage, between floating top and the tank skin annular space is arranged, this annular space has a sealing arrangement, make pot liquid when floating top cover fluctuates and atmospheric isolation, thereby significantly reduced the boil-off loss of liquid storage in storage process, also eliminated potential safety hazard to a certain extent.In order can be fluctuated in company with liquid storage in the jar in floating top, existing technology is that the floating drum or the buoyancy tank of aluminum alloy, corrosion-resistant steel or other material are installed in bottom, Fu Ding plane, relies on the buoyancy that floating drum or buoyancy tank produce and realizes that floating top swims in storage liquid surface all the time.Because liquid storage often has stronger corrosive property, so floating drum or buoyancy tank all need to select for use resistant material, cost is very expensive; No matter also have is floating drum, or buoyancy tank, all needs to take volume very big in the storage tank and just can reach the floating effect in floating top, thereby but the usage space of storage tank is reduced greatly.Floating top manufacture difficulty is big, the cost height, thereby the buoyancy on the floating top of prior art manufacturing is limited, so fire extinguishing is executed, fire extinguishing agent can only be stored in the tank body outside, when fire alarm occurring, fire extinguishing agent can only spray by pipeline, owing to can not in time putting out a fire the intensity of a fire is stretched.
Summary of the invention
The purpose of this utility model provides a kind of floating roof tank that has counter weight construction, and the floating roof tank of this structure has been simplified the integral structure of storage tank, has saved the productive costs and the maintenance cost of storage tank widely, has improved the safety performance of storage tank widely.
The technical scheme that realizes the utility model purpose is: a kind of floating roof tank that has counter weight construction, it is characterized in that on floating top, placing load-carrying, be provided with track adjusting wheel on floating roof tank, an end of rope or chain connects floating top, and the other end is walked around track adjusting wheel and is connected with counterweight.
Wherein counterweight can be 1,2 or a plurality of.
The utility model makes the buoyancy on the gravity of counterweight, floating top form a kind of equilibrium relation with institute's loads gravity and corresponding friction drag etc. on the gravity on floating top, the floating top by track adjusting wheel.When liquid storage was imported, liquid level rose, and buoyancy increases, and rose in floating top, and counterweight descends thereupon; When liquid storage was exported, liquid level descended, and buoyancy reduces, and floating top descends, and counterweight rises thereupon.The floating roof tank of this structure has been simplified the integral structure of storage tank, has saved the productive costs and the maintenance cost of storage tank widely; And various article such as required drainage facility, level detection, forewarn system, fire-fighting equipment, fire distinguisher, fire demand water can be placed on the floating top, can finish the injection of fire extinguishing agent, improve the safety performance of storage tank widely in moment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, floating top 2 is installed in the floating roof tank 1, is connected by track adjusting wheel 5 by rope or chain 4 between counterweight 3 and the floating top 2.Load-carrying 6 is the general name of various article such as the required level detection of storage tank, forewarn system, fire fighting equipment, fire distinguisher, fire demand water, the weight on floating top 2 equals the weight of counterweight 3 and the buoyancy sum on 7 pairs of floating tops 2 of liquid storage with the weight sum of load-carrying 6, track adjusting wheel 5 is finished the guiding of power, and floating top 2 swims on the liquid level of liquid storage 7 all the time.
When Hydraulic Pump input liquid, the volume of liquid storage increases, and liquid level rises, and buoyancy strengthens, and the balance of strength is broken, the upwards operation of floating top 2, and the downward operation along with the up of floating top 2 of counterweight 3 this moment; In the time of the Hydraulic Pump output liquid, the volume-diminished of liquid storage, liquid level descends, and buoyancy reduces, and the balance of strength is broken, the operation downwards of floating top 2, and the upwards operation along with the descending of floating top 2 of counterweight 3 this moment is in balance all the time to reach both sides strength.
Liquid storage 7 temperature that cause by factors such as temperature, heating, coolings, when volume changes, the inside liquid level of liquid storage 7 changes thereupon, will increase the buoyancy of floating drum 2 or alleviate buoyancy floating drum 2, with above-mentioned principle, counterweight 3 meeting downward operations along with the up of floating drum 2, the operation that also can make progress along with the descending of floating drum 2 is in balance all the time to reach both sides strength.
Counterweight 3 can be 1 counterweight, can be 2 counterweights, also can be a plurality of counterweights.Each counterweight can be upstream or downstream separately, also can be to coordinate upstream or downstream, can also be that a part is coordinated upstream or downstream.The coordination mode of counterweight 3 can be a mechanical interlock, can be electrical control, can also be numerical control, or their combination.
